1. I'm growing fewer annuals, biennials and bedding plants, and replacing them with hardy perennials:
I've planted perennial viola cornuta alba in the five pots on the steps which contained the delightful, but tender daisy erigeron karvinskianus which sadly all died this year. (In Cornwall a couple of weeks ago they were flowering out of every crevice and crack in every wall and pavement!) Also one big pot which used to be planted up every year with tender plants now has a lovely big plant of blue geranium 'Roxanne' which is completely hardy, with a generous and very long flowering season.
Less work and a similar effect....simpler..
